DETAILED DESCRIPTION

Described in detail herein is a multi-variant tracking system. A central computing system can be in communication with independently operated domains. Each independently operated domain can be associated with a cryptographically verifiable ledger represented by a sequence of blocks. Each block contains one or more transactions records and each subsequent block contains a hash value associated with the previous block. The central computing system can receive an alert of a creation of a new block in a cryptographically verifiable ledger associated with a first independently operated domain. The new block contains transaction records associated with a change in a first data value of a first type. The central computing system can determine one or more independently operated domains affected by a change in a first data value of a first type in response to receiving an alert that a new block in a cryptographically verifiable ledger associated with a first independently operated domain is created. The new block contains transaction records associated with the change in the first data value of the first type. The central computing system can determine a type of data value associated with other transaction records in each cryptographically verifiable ledger for each of the independently operated domains. The central computing system can convert the change in the first data value of the first type to a corresponding change in a data value of a different type of data value associated with transaction records in each cryptographically verifiable ledger for each of the independently operated domains. The central computing system can trigger additional new blocks containing transaction records associated with the change of the different type of data value to be generated in each cryptographically verifiable ledger associated with the independently operated domains.

The one or more independently operated domains can include a second independently operated domain. In response to triggering a new block containing transaction records associated with a change of a second data value of a second type in a cryptographically verifiable ledger associated with the second independently operated domain, the central computing system can be programmed to determine a third independently operated domain is affected by the change of the second data value of the second type. The third independently operated domain is different than the first independently operated domain and the second independently operated domains. In response to determining the third independently operated domain is affected by the change of the second data value of the second type, the central computing system is further programmed to convert the change of the second data value of the second type in a cryptographically verifiable ledger associated with the second independently operated domain to corresponding to a change of a third data value of a third type associated with transaction records in a cryptographically verifiable ledger associated with the third independently operated domain. In response to converting the change of the second data value of the second type in a cryptographically verifiable ledger associated with the second independently operated domain to the third data value of the third type associated with transaction records in a cryptographically verifiable ledger associated with the third independently operated domain, the computing system can be programmed to trigger a new block containing transaction records associated with the change in the third data value of the third type, to be generated, in a cryptographically verifiable ledger associated with the third independently operated domain.

The one or more transaction records are associated with a delivery of the at least one physical object. The data value is one or more of: a quantity of the at least one physical object, cost of the physical object, hours to deliver a physical object, type of the at least one physical object and size of the at least one physical object. The alert is the transfer of ownership of the at least one physical object. The central computing system is configured to receive the alert from one or more of a mobile device, a terminal or a computing device. The terminal is disposed in a facility in which the at least one physical object is disposed.

FIGS. 1A-1C are block diagrams illustrating a dataflow while using multiple blockchains in accordance with an exemplary embodiment. With reference to FIG. 1A, a blockchain system 100 can include multiple blockchains. The blockchains can store data for different types of data associated with a single event. In operation 101, an event can occur at a facility or in a remote location. In operation 102, the blockchain system 100 can decompose the event into the different component parts. In operation 106, the blockchain system 100 can determine how each domain is affected by the component parts of the event, in response to operation 104, in which the blockchain system 100 can import component dictionary/business rules to determine how each component is affected by the event.

As a non-limiting example, the blockchain system 100 can include a cash-on-hand domain, inventory domain, customer identification domain, N type information domain, customer/vendor identification domain (the customer/vendor identification domain can be external to the blockchain system 100), and a profit & loss (P&L) domain. In operations 108-110, the blockchain system 100 can transmit particular data associated with each domain affected by the event to the cash-on-hand domain, inventory domain, customer identification domain, N type information domain, customer/vendor identification domain, and/or the profit & loss (P&L) domain, respectively. Each domain can be associated to a respective blockchain. Each domain can instruct the respective blockchain to generate a new block in the cryptographically verifiable ledger including the data affected by the event for the respective domain. As an example, the cash-on-hand domain can be associated with a cash-on-hand blockchain; the inventory domain can be associated with an inventory blockchain; customer identification domain can be associated with a customer blockchain, N type information domain can be associated with an N blockchain, customer/vendor identification domain can be associated with a P&L blockchain specific for customers and vendors, and the profit & loss (P&L) domain can be associated with a P&L blockchain. In operations 120-130, the particular data associated with each domain affected by the event transmitted to each respective domain can be respectively stored in the corresponding blockchain; data particular to the cash-on-hand domain can be stored in the cash-on-hand blockchain, data particular to the inventory domain can be stored in the inventory blockchain, data particular to the customer identification domain can be stored in the customer blockchain, data particular to the N type information domain can be stored in the N type blockchain, data particular to the customer/vendor identification domain can be stored in the individual blockchains specific for customers and/or vendors, and data particular to the P&L domain can be stored in the P&L blockchain.

With reference to FIG. 1B, in operations 132-140, the blockchain system 100 can distribute the respective blockchain ledgers to peers computing devices in a distributed network. For example, peers can include one or more of: different facilities, regional data centers, and corporate data centers. The blockchain ledgers can include the particular data associated with each domain affected by the event. In operation 142, third party systems such as vendors can use Application Program Interfaces (APIs) to mine the received blockchain ledger. In operation 144, systems internal to the blockchain system 100 can mine the respective blockchain ledgers. In operation 146, the particular data associated with each domain affected by the event, mined by systems internal to the blockchain system 100 can be committed to a relational database associated with the respective domain.

With reference to FIG. 1C, a blockchain system 100 can include a master blockchain and sub-blockchains (i.e., blockchains associated with the individual domains). In operation 152, a data associated with the event can be stored in a master blockchain. In operation 154, the master blockchain can be polled for new data. In operation 156, the data from the event can be from master blockchain and disseminated to the sub-blockchains.

FIG. 2A is a block diagram illustrating components of a multi-variant tracking system 200 in accordance with an exemplary embodiment. The multi-variant tracking system 200 can include multiple independently operated domains. Each independently operated domain can be associated with a cryptographically verifiable ledger represented by a sequence of blocks. Each block can contain one or more transactions records and each subsequent block can contain a hash value associated with the previous block. The multi-variant tracking system 200 can also include a master (or daily) cryptographically verifiable ledger. In operation 202, the multi-variant tracking system 200 can receive an event. The event can include transaction records including first data values of a first type. The multi-variant tracking system 200 can determine data stored in the blocks of the cryptographically verifiable ledgers of the independently operated domains that are affected by the event. The multi-variant tracking system 200 can determine a type of data values associated with other transaction records in each cryptographically verifiable ledger for the independently operated domains that are affected by the event. In operation 203, the multi-variant tracking system 200 can convert the first data value of the first type to a corresponding change in a data value of a different type of data value associated with transaction records in each cryptographically verifiable ledger for each of the independently operated domains that are affected by the event. In operation 204, additional new blocks containing transaction records associated with the change of the different type of data value can be generated in each cryptographically verifiable ledger associated independently operated domains that are affected by the event. In operation 206, a new block including data of the original type of data values included in the event can be generated in the master cryptographically verifiable ledger.

In one embodiment, in operation 208, the multi-variant tracking system 200 can receive an event. The event can include first data values of a first type. The multi-variant tracking system can determine data stored in the cryptographically verifiable ledgers of the independently operated domains that are affected by the event. The multi-variant tracking system 200 can determine a type of data value associated with other transaction records in each cryptographically verifiable ledger for the independently operated domains that are affected by the event. In operation 209, the multi-variant tracking system 200 can convert the first data value of the first type to a corresponding change in a data value of a different type of data value associated with transaction records in each cryptographically verifiable ledger for each of the independently operated domains that are affected by the event. The multi-variant tracking system 200 can determine if a specific data value is dependent on a change in data values in one or more different cryptographically verifiable ledgers. The multi-variant tracking system 200 can derive the change in the specific data value from the change in data values in the one or more different cryptographically verifiable ledgers. In operation 210, additional new blocks containing transaction records associated with the change of the different type of data value can be generated in each cryptographically verifiable ledger associated independently operated domains, affected by the event. In operation 212, a new block including data of the original type of data values included in the event can be generated in the master cryptographically verifiable ledger.

Each independently operated domain can be associated with a distinct cryptographically verifiable ledger represented by a sequence of blocks. Each block can contain one or more transactions records and each subsequent block contain a hash value associated with the previous block. In operation 222, the exception handling system 220 can receive an event including transaction records. In operation 224, a first independently operated domain can generate a new block in the cryptographically verifiable ledger associated with the independently operated domain. The new block can store the transaction records associated with the event. In operation 226, the exception handling system 220 can receive an alert of the creation of the new block storing the transaction records of the event in the cryptographically verifiable ledger of the first independently operated domain. The exception handling system 220 can initiate a smart contract based on the transaction records stored in the cryptographically verifiable ledger of the first independently operated domain. As an example, the smart contract can include a triggering event based on the transaction records of the event. The triggering event can be a specified threshold.

In operation 228, the exception handling system 220 can determine whether the threshold (i.e., triggering event) has been satisfied. If not, the process waits for the next event. In response the determining the threshold has been satisfied, the exception handling system 220 can identify an error in one or more of the independently operated domains that are different than the first independently operated domain. In operation 230, a message indicating the error can be transmitted to the one or more independently operated domains. In operation 232, the exception handling system 220 can store the error in a relational database. In operation 234, the exception handling system 220 can trigger creation of additional new blocks in each cryptographically verifiable ledger associated with the one or more of the plurality of independently operated domains. The additional new blocks can contain information associated with the error. The exception handling system can trigger an action to resolve the error for each of the one or more independently operated domains.

FIG. 5 is a block diagram illustrating components of a multiple blockchain system in accordance with an exemplary embodiment. The multiple blockchain system 500 can include multiple layers of blockchains. Each blockchain can include a cryptographically verifiable ledger represented by a sequence of blocks. Each block can contain one or more transactions records and each subsequent block can contain a hash value associated with the previous block. Each blockchain can have a parent/child and/or sibling relationship with another blockchain. The first block in the child blockchain can include a hash value to a block in the parent blockchain. The parent blockchains can spawn and purge children blockchains.

The multiple blockchain system 500 can include a master blockchain 502 and sub-blockchains 504-524. The master blockchain 502 can be included in a central computing system (not shown in FIG. 5) and the sub-blockchains 504-524 can be included in sub-computing systems (not shown in FIG. 5). The central computing system and the sub-computing systems can include one or more servers, one or more computing devices, one or more processing device, and/or one or more nodes in a distributed network, to control the operations of the master and sub-blockchains. The master blockchain 502 may not have an associated parent blockchain. The multiple blockchain system 500 can further include sub-blockchains 504-508. The master blockchain and sub-blockchains 504-508 can have a direct parent-child relationship. The master blockchain 504-508 can spawn the sub-blockchains 504-508 in response to receiving an event. The multiple blockchain system 500 can have further sub-blockchains 510-512 with a direct parent-child relationship with sub-blockchain 504. The multiple blockchain system 500 can have further sub-blockchains 514-516 with a direct parent-child relationship with sub-blockchain 512. The multiple blockchain system 500 can have further sub-blockchains 518-520 with a direct parent-child relationship with sub-blockchain 516. The multiple blockchain system 500 can have further sub-blockchains 522-524 with a direct parent-child relationship with sub-blockchain 518.

As described above, the master blockchain can receive an event including transaction records. The central computing system can identify one or more of the sub-blockchains 504-508 affected by the event. The central computing system can transmit the event including the transaction records to one or more of the sub-computing systems including the sub-blockchains 504-508 affected by the event. In one embodiment, the central computing system can spawn the one of the sub-blockchains 504-508 in the sub-computing systems, prior to transmitting the event and the transaction records. As an example, the central computing system can transmit the event and transaction records to the sub-computing system and trigger a new block to be generated in the cryptographically verifiable ledger associated with the sub-blockchain 504. The new block can include the transaction records from the event.

The sub-computing system of the sub-blockchain 504 can identify sub-computing systems of the sub-blockchains 510-512 are affected by the event. The sub-computing system of the sub-blockchain 504 can transmit the event and transaction records to the sub-computing systems of the sub-blockchain 510 and sub-blockchain 512 and trigger a new block to be generated in the cryptographically verifiable ledger associated with the sub-blockchain 510 and sub-blockchain 512. The new block can include the transaction records from the event.

The sub-computing system of the sub-blockchain 512 can identify sub-computing systems of the sub-blockchains 514-516 are affected by the event. The sub-computing system of the sub-blockchain 512 can transmit the event and transaction records to the sub-computing systems of the sub-blockchain 514 and sub-blockchain 516 and trigger a new block to be generated in the cryptographically verifiable ledger associated with the sub-blockchain 514 and sub-blockchain 516. The new block can include the transaction records from the event.

The sub-computing system of the sub-blockchain 516 can identify sub-computing systems of the sub-blockchains 518-520 are affected by the event. The sub-computing system of the sub-blockchain 516 can transmit the event and transaction records to the sub-computing systems of the sub-blockchain 518 and sub-blockchain 520 and trigger a new block to be generated in the cryptographically verifiable ledger associated with the sub-blockchain 518 and sub-blockchain 520. The new block can include the transaction records from the event.

The sub-computing system of the sub-blockchain 518 can identify sub-computing systems of the sub-blockchains 522-524 are affected by the event. The sub-computing system of the sub-blockchain 518 can transmit the event and transaction records to the sub-computing systems of the sub-blockchain 522 and sub-blockchain 524 and trigger a new block to be generated in the cryptographically verifiable ledger associated with the sub-blockchain 522 and sub-blockchain 524. The new block can include the transaction records from the event.

Each blockchain can store different types of data values. The parent blockchains can identify the type of data values stored in the child blockchains. The parent blockchains can convert the type of data value stored in the parent blockchain to a type of data value stored in the child blockchain for the transaction records associated with the event. The types of data values can be one or more of, monetary currency, labor costs, inventory costs, and/or temporal costs.

As described above, the parent blockchain can purge a child blockchain based on an event satisfying threshold requirements (i.e., as set forth in a smart contract). As an example, the sub-blockchain 512 can purge and/or archive sub-blockchain 514 based on a received event.

FIG. 6 illustrates an exemplary network diagram of an embodiment of the multi-variant tracking system 200 in accordance with an exemplary embodiment. In the present example embodiment, the multi-variant tracking system 200 can include one or more data storage devices 605, one or more central computing systems 602, one or more independently operated domains 640, and one or more third party systems 660. The central computing system 602 can be in communication with the data storage devices 605, the independently operated domains 640 and third party systems 660, via a communications network 615. The central computing system 602 can execute at least one instance of a decision engine 606.

Each of the independently operated domains 640 can include a management system 610 and a node 642. The node 642 can store a copy of a blockchain record and/or a shared ledger storing data associated events of data associated with the independently operated domain 640. The blockchain can be embodied as distinct cryptographically verifiable ledger represented by a sequence of blocks, each block containing one or more transactions records and each subsequent block containing a hash value associated with the previous block.

In an example embodiment, one or more portions of the communications network 615 can be an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless wide area network (WWAN), a metropolitan area network (MAN), a portion of the Internet, a portion of the Public Switched Telephone Network (PSTN), a cellular telephone network, a wireless network, a WiFi network, a WiMax network, another type of network, or a combination of two or more such networks.

The central computing system 602 includes one or more computers or processors configured to communicate with the data storage devices 605, and the independently operated domains 640. The data storage devices 605 can store information/data, as described herein. For example, the data storage devices 605 can include an events database 630, a physical objects database 635, and a domain database 637. The events database 630 can be embodied relational database configured to store information associated with an event. As a non-limiting example, the event database 630 can store transaction records associated with physical objects such as invoices, purchase orders, inventory records, sales/returns records, vendor orders, claims, shipping orders, and/or receiving orders. The physical objects database 635 can store information associated with physical objects disposed at a facility. The domain database 637 can store information associated with independently operated domains. The data storage devices 605 and the central computing system 602 can be located at one or more geographically distributed locations from each other. Alternatively, the data storage devices 605 can be included within the central computing system 602.

In an exemplary embodiment, an independently operated domain 640 can receive an alert of an occurrence of an event including transaction records from a third party system 660. The event can be associated with one or more physical objects. In response to receiving the event, the independently operated domain can execute the management system 610. The management system 610 can query the physical object database 635 to verify the transaction records of the event. The node 642 of the independently operated domain 640 can generate new block in the cryptographically verifiable ledger of the sub blockchain, including the transaction records of the event in the sub blockchain. The transaction records can be associated with a change in a first data value of a first type.

The central computing system 602 can receive an alert of the new block created in the independently operated domain 640. The central computing system 602 can execute the decision engine 606 in response to receiving the alert. The decision engine 606 can query the physical objects database 635 to retrieve additional data associated with the physical objects which may affect other independently operated domains. The decision engine 606 can identify independently operated domains 640 for which data would be affected by the change in a first data value of a first. The identified independently operated domains 640 can be different than the independently operated domain 640 which generated the new block. The decision engine 606 can query the domains database 637 to determine a type of data value associated with each of other transaction records in each cryptographically verifiable ledger for each of the affected independently operated domains. The decision engine 606 can convert the change in the first data value of the first type to a corresponding change in a data value of a different type of data value associated with transaction records in each cryptographically verifiable ledger for each of the affected independently operated domains 640. In one embodiment, the decision engine 606 can query the domain domains database 637 to determine the conversion rate between the data values. The decision engine 606 can trigger additional new blocks containing transaction records associated with the change of the different type of data value to be generated in each cryptographically verifiable ledger associated with the affected independently operated domains 640. The new blocks can include transaction records associated with the event and of a data type specific to the independently operated domain 640. The node 642 of the affected independently operated domains 640 can generate the new blocks in the respective cryptographically verifiable ledgers of each of the affected independently operated domains 640.

In response to triggering the generation of the new blocks in the affected independently operated domains 640, the decision engine 606 can identify further independently operated domains 640, different than the independently operated domains 640 including the new blocks, affected by the generation of the new blocks in the independently operated domains 640. The decision engine 606 can determine query the domain database 637 to determine the data values specific to the further independently operated domains 640 and a conversion rate between the data values. The decision engine 606 can convert the change of the data value of the transaction records of the new blocks generated in the independently operated domains 640 to the data value of the transaction records in a cryptographically verifiable ledger associated with the further independently operated domains 640, based on the conversion rate. The decision engine 606 can trigger the generation of new blocks including the converted change in value to the respective data type, in each of the cryptographically verifiable ledgers associated with the further independently operated domains 640.

The one or more transaction records are associated with a delivery of the at least one physical object. For example, data value is one or more of: a quantity of the at least one physical object, cost of the physical object, hours to deliver a physical object, type of the at least one physical object and size of the at least one physical object. The event is the transfer of ownership of the at least one physical object.

In one embodiment, the received event data can be and archived stored in the event database 630. As described above, the event database 630 can be a relational database.

As a non-limiting example, system for multi-variant tracking system 200 can be implemented in a retail store and/or e-commerce environment. For example, the independently operated domains 640 can be domains for storing and processing inventory, sales, purchase orders, or retail store stock rooms. The physical objects can be embodied as products sold at the retail store and/or e-commerce website.

In one example, one independently operated domain 640 can be embodied as an inventory domain and another independently operated domain 640 can be embodied as an labor domain. The inventory domain can transmit an event associated with shipping of products from a warehouse to a retail store. The node 642 of the inventory domain can generate a new block in the cryptographically verifiable ledger of the inventory domain associated including the event and the transaction records associated with the event. The cryptographically verifiable ledger of the inventory domain can store transaction records of a data value associated with inventory of products. The event can be a shipment of new inventory arriving at a warehouse. The transaction records can include a change in inventory value based on the new shipment. The central computing system 602 can receive an alert of the new block being created.

In response to receiving the alert, the decision engine 606 can query the physical objects database 635 to identify independently operated domains 640 for which data would be affected by the transaction records of the event. The decision engine 606 can identify the labor domain has an independently operated domain that is affected by the transaction records of the shipment of products from the warehouse to the retail store. The decision engine 606 can query the domain database 637 to determine the type of data value stored in the transaction records of the cryptographically verifiable ledger of the labor domain. As an example, the type of data value can be amount of wages and hours necessary to complete a task, such as unloading new inventory.

The decision engine 606 can query the domain database 637 to determine the conversion rate between the changes in data values in the inventory domain to the change in data values in the labor domain. The decision engine 606 can convert the change in data value associated with the new shipment of products to the change in wages and hours necessary of unloading the new shipment of products. The decision engine 606 can trigger generation of a new block in the cryptographically verifiable ledger associated with the labor domain. The new block can include transaction records indicating a change in data value of the wages and hours necessary of unloading the new shipment of products.

Descriptions of some embodiments of blockchain technology are provided with reference to FIGS. 7-10 herein. In some embodiments, blockchain technology may be utilized for exception handling in a distributed system as described herein. One or more of the independently operated domains as described herein may comprise a node in a distributed blockchain system storing a copy of the blockchain record. Updates to the blockchain may comprise information associated with events associated with physical objects received by the independently operated domains, and one or more nodes on the system may be configured to incorporate one or more events into blocks to add to the distributed database.

Distributed database and shared ledger database generally refer to methods of peer-to-peer record keeping and authentication in which records are kept at multiple nodes in the peer-to-peer network instead of being kept at a trusted party. However, exemplary embodiments of the present disclosure can also utilize a private (trusted) system to maintain the blockchains. A blockchain may generally refer to a distributed database that maintains a growing and ordered list or chain of records in which each block contains a hash of some or all previous records in the chain to secure the record from tampering and unauthorized revision. A hash generally refers to a derivation of original data. In some embodiments, the hash in a block of a blockchain may comprise a cryptographic hash that is difficult to reverse and/or a hash table. Blocks in a blockchain may further be secured by a system involving one or more of a distributed timestamp server, cryptography, public/private key authentication and encryption, proof standard (e.g. proof-of-work, proof-of-stake, proof-of-space), and/or other security, consensus, and incentive features. In some embodiments, a block in a blockchain may comprise one or more of a data hash of the previous block, a timestamp, a cryptographic nonce, a proof standard, and a data descriptor to support the security and/or incentive features of the system.

In some embodiments, the exception handling system comprises a distributed timestamp server comprising a plurality of nodes configured to generate computational proof of record integrity and the chronological order of its use for content, trade, and/or as a currency of exchange through a peer-to-peer network. In some embodiments, when a blockchain is updated, a node in the distributed timestamp server system takes a hash of a block of items to be timestamped and broadcasts the hash to other nodes on the peer-to-peer network. The timestamp in the block serves to prove that the data existed at the time in order to get into the hash. In some embodiments, each block includes the previous timestamp in its hash, forming a chain, with each additional block reinforcing the ones before it. In some embodiments, the network of timestamp server nodes performs the following steps to add a block to a chain: 1) new activities are broadcasted to all nodes, e.g., resulting from in-field authentication of autonomous electronic devices, 2) each node collects new activities into a block, 3) each node works on finding a difficult proof-of-work for its block, 4) when a node finds a proof-of-work, it broadcasts the block to all nodes, 5) nodes accept the block only if activities are authorized, and 6) nodes express their acceptance of the block by working on creating the next block in the chain, using the hash of the accepted block as the previous hash. In some embodiments, nodes may be configured to consider the longest chain to be the correct one and work on extending it.

Now referring to FIG. 7, an illustration of a blockchain according to embodiments of the present disclosure is shown. As mentioned in above, with reference to FIG. 6, a blockchain comprises a hash chain or a hash tree in which each block added in the chain contains a hash of the previous block. In FIG. 7, block 0 700 represents a genesis block of the chain and can be generated in response to an event received associated with one or more physical objects. The block 0 700 can include information associated with the event associated with the physical objects and a hash key and a timestamp. The information associated with the event received associated with one or more physical objects can include information associated with the physical objects and information associated with the event, such as the delivery of the physical object, a quantity of the at least one physical object, name of the at least one physical object, type of the at least one physical object and size of the at least one physical object, and/or transfer of the ownership of physical objects. Block 1 710 can be generated in response to a verification of the event. The block 1 710 can contain a hash of block 0 700. The block 1 710 can include the information associated with the event and the physical objects. Otherwise, the block 1 710 can include information that an event was not verified. Additional blocks can be generated as additional requests are received and each block that is generated can include a hash of a previous block. For example, block 2 720 can be generated in response to a subsequent request and can contain a hash of block 1 710, block 3 730 can be generated in response to a yet another subsequent request and can contain a hash of block 2 720, and so forth. Continuing down the chain, block N contains a hash of block N−1. In some embodiments, the hash may comprise the header of each block. Once a chain is formed, modifying or tampering with a block in the chain would cause detectable disparities between the blocks. For example, if block 1 is modified after being formed, block 1 would no longer match the hash of block 1 in block 2. If the hash of block 1 in block 2 is also modified in an attempt to cover up the change in block 1, block 2 would not then match with the hash of block 2 in block 3. In some embodiments, a proof standard (e.g. proof-of-work, proof-of-stake, proof-of-space, etc.) may be required by the system when a block is formed to increase the cost of generating or changing a block that could be authenticated by the consensus rules of the distributed system, making the tampering of records stored in a blockchain computationally costly and essentially impractical. In some embodiments, a blockchain may comprise a hash chain stored on multiple nodes as a distributed database and/or a shared ledger, such that modifications to any one copy of the chain would be detectable when the system attempts to achieve consensus prior to adding a new block to the chain. In some embodiments, a block may generally contain any type of data and record. In some embodiments, each block may comprise a plurality of transaction and/or activity records.

In some embodiments, the blocks generated by a computing system can contain rules and data for authorizing different types of actions and/or parties who can take action as described herein. In some embodiments, transaction and block forming rules may be part of the software algorithm on each node. When a new block is being formed, any node on the system can use the prior records in the blockchain to verify whether the requested action is authorized. For example, a block may contain a public key associated with the user of a user device that purchased/acquired the physical object, this design that allows the user to show possession and/or transfer the digital license using a private key. Nodes may verify that the user is in possession of the one or more physical objects and/or is authorized to transfer the one or more physical objects based on prior events when a block containing the transaction is being formed and/or verified. In some embodiments, rules themselves may be stored in the blockchain such that the rules are also resistant to tampering once created and hashed into a block. In some embodiments, the blockchain system may further include incentive features for nodes that provide resources to form blocks for the chain. Nodes can compete to provide proof-of-work to form a new block, and the first successful node of a new block earns a reward.

Now referring to FIG. 8, an illustration of blockchain-based transactions according to some embodiments is shown. In some embodiments, the blockchain illustrated in FIG. 8 comprises a hash chain protected by private/public key encryption. Transaction A 810 represents an event in a block of a blockchain showing that recipient 1 (e.g., an independently operated domain creating a new block with transaction records associated with physical objects, based on a received event). Transaction A 810 contains recipient's 1 public key and recipient 0's signature for the transaction and a hash of a previous block. When recipient 1, central computing system transmits an alert including the public key and private key, to an independently operated domain, of the newly generated block storing the transaction records, in a different independently operated domain, and the independently operated domain accesses the transaction record, a block containing transaction B 820 is formed. The record of transaction B 820 comprises the public key of recipient 2, a hash of the previous block, and recipient 1's signature for the transaction that is signed with the recipient 1's private key 825 and verified using recipient 1's public key in transaction A 810. If recipient 2 (e.g., the independently operated domain) transmits an alert including the public key and private key, to an independently operated domain, of the newly generated block storing the transaction records to recipient 3 (a different independently operated domain), a block containing transaction C 830 is formed. The record of transaction C 830 comprises the public key of recipient 3, a hash of the previous block, and recipient 2's signature for the transaction that is signed by recipient 2's private key 835 and verified using recipient 2's public key from transaction B 820.

In some embodiments, when each event is created, the system may check previous events and the current recipient's private and public key signature to determine whether the transaction is valid. In some embodiments, transactions are broadcasted in the peer-to-peer network and each node on the system may verify that the transaction is valid prior to adding the block containing the transaction to their copy of the blockchain. In some embodiments, nodes in the system may look for the longest chain in the system to determine the most up-to-date event to prevent the current recipient from double spending the asset. The transactions in FIG. 8 are shown as an example only. In some embodiments, a blockchain record and/or the software algorithm may comprise any type of rules that regulate who and how the chain may be extended. In some embodiments, the rules in a blockchain may comprise clauses of a smart contract that is enforced by the peer-to-peer network.

Now referring to FIG. 9, a system according to some embodiments is shown. The exception handling system comprises a plurality of nodes 910 communicating over a network 920. In some embodiments, the nodes 910 may comprise a distributed blockchain server and/or a distributed timestamp server. Each node 910 in the system comprises a network interface 911, a control circuit 912, and a memory 913.

The control circuit 912 may comprise a processor, a microprocessor, and the like and may be configured to execute computer-readable instructions stored on a computer-readable storage memory 913. The computer-readable storage memory may comprise volatile and/or non-volatile memory and have stored upon it a set of computer-readable instructions which, when executed by the control circuit 912, causes the node 910 update the blockchain 914 stored in the memory 913 based on communications with other nodes 910 over the network 920. In some embodiments, the control circuit 912 may further be configured to extend the blockchain 914 by processing updates to form new blocks for the blockchain 914. Generally, each node may store a version of the blockchain 914, and together, may form a distributed database. In some embodiments, each node 910 may be configured to perform one or more steps described with reference to FIGS. 7-9 herein.

The network interface 911 may comprise one or more network devices configured to allow the control circuit to receive and transmit information via the network 920. In some embodiments, the network interface 911 may comprise one or more of a network adapter, a modem, a router, a data port, a transceiver, and the like. The network 920 may comprise a communication network configured to allow one or more nodes 910 to exchange data. In some embodiments, the network 920 may comprise one or more of the Internet, a local area network, a private network, a virtual private network, a home network, a wired network, a wireless network, and the like. In some embodiments, the system does not include a central server and/or a trusted third party system. Each node in the system may enter and leave the network at any time.

With the system and processes shown, once a block is formed, the block cannot be changed without redoing the work to satisfy census rules thereby securing the block from tampering. A malicious attacker would need to provide proof standard for each block subsequent to the one he/she seeks to modify, race all other nodes and overtake the majority of the system to affect change to an earlier record in the blockchain.

FIG. 11 is a flowchart illustrating an exemplary process of an embodiment of a multi-variant tracking system in accordance with the present disclosure. A central computing system can be in communication with independently operated domains. Each independently operated domain can be associated with a cryptographically verifiable ledger represented by a sequence of blocks. Each block contains one or more transactions records and each subsequent block contains a hash value associated with the previous block. In operation 1100, the central computing system can receive an alert of a creation of a new block in a cryptographically verifiable ledger associated with a first independently operated domain. The new block contains transaction records associated with a change in a first data value of a first type. In operation 1102, the central computing system can determine one or more independently operated domains affected by a change in a first data value of a first type in response to receiving an alert that a new block in a cryptographically verifiable ledger associated with a first independently operated domain is created. The new block contains transaction records associated with the change in the first data value of the first type. In operation 1104, the central computing system can determine a type of data value associated with other transaction records in each cryptographically verifiable ledger for each of the independently operated domains. In operation 1106, the central computing system can convert the change in the first data value of the first type to a corresponding change in a data value of a different type of data value associated with transaction records in each cryptographically verifiable ledger for each of the independently operated domains. In operation 1108, the central computing system can trigger additional new blocks containing transaction records associated with the change of the different type of data value to be generated in each cryptographically verifiable ledger associated with the independently operated domains.
